Arc network · proof-of-work gate · 20,000 blocks

Every block is found in your browser.

ω(b) = 10⁴ · 2^{−⌊b/1,200⌋}

The puzzle is a single keccak256 over your own address, the current block number and a nonce you search for locally. Nothing leaves your machine until a nonce is found — then one transaction commits it and mints the reward. No account, no allowlist, no server in the loop.

Read-only RPC

Chain state is read directly from the RPC — no wallet needed for reads.
Mainnet 5042: rpc.mainnet.arc.io (official endpoint, CORS reflects any origin). Testnet 5042002: rpc.testnet.arc.io (its CORS allowlist accepts only pages served from vresarc.xyz).

§03 — SEARCH & COMMIT

hashrate 0 H/s

If another miner lands the block first the transaction reverts and only gas is lost.

Connect

Any injected wallet. Switch to the Arc network and load the contract address — state is read straight from the chain, not from this page.

Search

Your browser hashes keccak256(miner ‖ block ‖ nonce) until the digest falls under the current target. At 2^20 that is seconds of work; the target doubles every 1,200 blocks.

Commit

One signature submits the nonce. The contract re-derives the target, verifies the digest and mints the scheduled reward.
